OUTBOARD BUOY FOR BOATS.

Application filed January 3, 1922.

T 0 aZZ whom it may concern Be it known that I, GUsrAvn HAAOK, a citizenof the United States, residing at Madison, in the county of Dane andState of Wisconsin, have invented certain new and useful Improvements inOutboard Buoys for Boats, of which the following is a speci fication.

My invention relates to outboard buoys for boats; and the objects of myinvention are, first, to provide an outboard tubular air chamber to beattached to both sides of a boat, between the water-line and gunnel;second, to provide brackets to be attached to the stem and sides of theboat with a plurality of holes for locating the tubes at dif ferentdistances from the gunnel; third, to provide closures for the ends ofthe tubes with projecting plates adapted to be secured to the bracketsby screws or bolts; and fourth, to have metal nipples and check valvesdisposed in the front closures for admitting and retaining compressedair in the tubes.

I attain these objects by the mechanism shown in the accompanyingdrawing in which Fig. 1, is a plan;

Fig. 2, is a side elevation;

Fig. 3, is an end elevation of the aft closure Fig. 4, is a sideelevation of same attached to tube;

Fig. 5, is a rear elevation of after bracket;

Fig. 6, is afront elevation of same;

Fig. 8, is a plan of the stem bracket;

Fig. 7, is a side elevation of same.

Similar numerals refer to similar parts throughout the several views.

The air tubes 1, are preferably of alu- Specification of Letters Patent.

minuin with an end closure 2, soldered to the rear end of same, saldclosure being provided with an outwardly extending plate 8,

adapted to be fastened to a bracketi, on the outside of a boat by screws5. A somewhat similar closure 6, is soldered to the front ends of thetubes, with a valve 7, for admitting and retaining compressed air, aplate 8, extends forward from the closure adapted to be secured to abracket 9, by a bolt 10, said bracket 9, to be securely fastened to thestem of the boat by screws or rivets 11.

The tubes 1, as described will add buoyancy to a boat in a rough sea andprevent the bow being submerged, and also prevent dangerous rolling andcapsizing as the rolling is arrested by the tubes before the waterreaches the gunnel.

ltlaving thus described my invention, I claim.

in a device of the kind described, closed metal tubes containingcompressed air and extending along both sides of a boat between thewater-line and gunnehsaid tubes provided with plates extending outwardfrom the ends thereof, a bracket with a plurality of holes secured tothe stem of the boat and the forward plates fastened to the bracket by abolt, brackets secured to both sides of the boat, a plurality of holesthrough said brackets in which screws are disposed for attaching theplates at the rear ends of the tubes thereto, and means for admittingand retaining compressed air in the tubes.

In testimony whereof I affix my signature in the presence of twosubscribing witnesses.
